I am hearing a loud
The noise could be one of the cooling fans has some debris in it or the most likely cause is the color wheel is starting to fail and will have to be replaced. If the picture starts to have color or picture problems then it is the color wheel.

Red light temp comes on
Hey thompsonsrj, basing my answer only what little I have learned about one part of your problem you pointed out the screeching sound... my tv also did this and I discovered through research that it is indicative of the Color Wheel going bad. It is a $100 or so dollar part and can be replaced with a bit of elbow grease. As far as the overheating, possible cooling fan issue, I am unsure if they are related? I hope this helps a little? Thanks, Will

you have a bad board, maybe the power supply/deflection board, maybe the signal board, to troubleshoot this problem you need a qualified tv repairman. or you could replace the whole board yourself, the power supply board is about $200, the signal module is about $500, i'd start with the cheaper one, or hope the repairman can fix it at component level.
